"I use my off duty time to investigate scientific curiosities of my own design, because I'm here, and I can, and these things tickle my imagination." This awesome nugget of inspiration comes to you from NASA astronaut and chemist Don Pettit, who is currently hanging out, sans gravity, on the International Space Station. While he's not making discoveries about outer space and hunting for aliens (I assume), he conducts fun experiments to see what happens to earthly elements in outer space. That involves doing Yo-Yo tricks in space, and then getting to name them whatever he wants because he's the first person to do zero gravity Yo-Yo tricks. Way to make everyone else feel totally inadequate about their accomplishments, Don Pettit.
